History

Interstate 787 was planned as The Riverfront Route along the Hudson River in Albany during the early 1950s.¹ I-787 was part of the proposed urban Interstate numerology for New York approved by the American Association of State Highway Officials (AASHO) on November 10, 1958. The number was the result of being the 4th spur branch in order from south to north in the state as the numbering plan developed:

• I-187 - proposed Cross-Westchester Expressway east from I-87 (New York Thruway) to I-95 at Port Chester, revised to I-487, and ultimately became a part of I-287.
• I-387 - proposed New York Thruway west from I-87 at Elmsford across the Tappan Zee Bridge to Suffern, became part of I-287 and ultimately part of a westward realignment of I-87 off what became I-684.
• I-587 - spur into Kingston.
